What indoor plants help to reduce indoor air pollution?

Answers

NASA has done quite a bit of study on this issue and found house plants to be so efficient in reducing indoor air pollution, it plans to send a few into space on future trips. Studies showed Philodendron, Spider plant, and Golden Pothos (Devil’s Ivy) best at eliminating formaldehyde. Dracaena Massangeana (Corn Plant), Spathiphyllum (Peace Lily), and Golden Pathos were all good at removing benzene, but Gerbera daisy and Chrysanthemums were best at it.

It’s not only the leaves that work to remove the chemical vapors, the root and soil bacteria contribute to the process as well.
